The Navigo™ system tracks and records the location of the ultrasound probe and the incoming video from the ultrasound system. The patient's movement is recorded and compensated when the ultrasound images are placed with reference to each other. In post procedure, the physician defines the boundaries of the prostate on selected ultrasound images and a 3D model of the prostate is displayed with all recorded biopsy specimens' locations displayed in the prostatic volume. The physician will be able to examine in post analysis the scattering quality of the biopsy specimens in the prostatic volume and update the pathology results. The 3D model can be rotated, manipulated and displayed in the physician's preferable choice.
